TC7SET08FU from TOSHIBA LJ CT, in a SOT-353. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	IN B	input	AND gate input B. CMOS input with TTL-compatible thresholds (VIH = 2.0 V min, VIL = 0.8 V max). 5.5 V tolerant regardless of VCC. Must not be left floating; tie unused inputs to VCC or GND.
2	IN A	input	AND gate input A. CMOS input with TTL-compatible thresholds (VIH = 2.0 V min, VIL = 0.8 V max). 5.5 V tolerant regardless of VCC. Must not be left floating; tie unused inputs to VCC or GND.
3	GND	power_in	Ground reference (0 V). Return path for supply and signal currents.
4	OUT Y	output	AND gate output Y = A AND B. CMOS push-pull output; drives VOH >= 4.4 V at IOH = -50 uA and VOL <= 0.1 V at IOL = 50 uA (VCC = 4.5 V). Rated for +/-8 mA drive.
5	VCC	power_in	Positive supply, 4.5 V to 5.5 V operating range (7.0 V absolute max). Quiescent supply current ICC = 2.0 uA max at Ta = 25 C. Decouple with 0.1 uF close to the pin.

TC7SET08FU

CAD (KiCad official)

Symbol: TC7SET08FU
Footprint: Package_TO_SOT_SMD:SOT-353_SC-70-5
3D model: SOT-353 (KiCad packages3D, STEP)

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tc7set08fu.step`	87 KB	You want the bare part, or you mark your own boards.
`tc7set08fu-etched.step`	1.9 MB	You want the part with `TC7SET08FU` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 466 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
